A needle assembly is disclosed. The needle assembly includes a housing having a flash chamber, and having a distal end and a proximal end engageable with a specimen collection container. The assembly includes a cannula having a patient end, a non-patient end, and a sidewall extending therebetween defining a cannula interior. The patient end of the cannula projects at least partially from the distal end of the housing, and the cannula interior is in fluid communication with the flash chamber. The assembly further includes a shield restrainably engaged with a portion of the housing and axially transitionable over the patient cannula from a retracted position in which the patient end is exposed, to an extended position in which the patient end is shielded by at least a portion of the shield, wherein at least a portion of the flash chamber is visible in the retracted position.

Lancet device includes a housing, a removable front cap mounted to the housing, a lancet holding member, and a trigger. A system is utilized for placing the lancet device in a trigger-set or armed position. A depth adjustment system includes a member that is at least partially rotatably mounted and that has an axis of rotation arranged substantially perpendicular to a center axis of the lancet holding member. An ejection system is utilized for at least one of preventing axial movement of the lancet holding member and removing or ejecting a lancet from the lancet holding member.

The Invention comprises a body, an actuator pivotally connected to the body, and a retractable needle adapted to provide fluid communication between a patient and a fluid collection tube, typically a blood collection tube, attachable to the device. A significant feature of the subject device is a retraction cavity disposed inside the actuator that is manually positionable to receive a portion of the needle retraction assembly following removal of the blood collection tube. Retraction is initiated by depressing the forwardly extending end of the actuator relative to the body, thereby causing a retainer clip to release the needle holder, after which the needle holder and a part of the needle are propelled into the retraction cavity by expansion of a compressed spring. The needle is thereby withdrawn from the patient and into the housing, reducing the likelihood of accidental needle sticks and preventing reuse of the device.

A blood collection assembly includes a housing and a cannula extending distally from the housing including a patient end, and a cannula shield removably engaged with a portion of the housing. The cannula shield is capable of shielding at least the patient end of the cannula, and includes a safety shield engagement. The assembly includes a pivoting safety shield engaged with a portion of the housing, which is transitionable from a retracted position in which the patient end of the cannula is exposed, to an extended position in which the patient end of the cannula is shielded by at least a portion of the safety shield. The safety shield includes at least one locking tab releasably engageable with the safety shield engagement, wherein the locking tab is fixedly engageable with a portion of the housing in the extended position.
